resistivity profiling services

  • Resistivity Surveys by Profiling Technique

    Soil testing by electrical profiling method the same arrays as for sounding (Schlumberger's, Wenner's etc.) are used. Electrical profiling is a basic resistivity survey technique about moving the whole array along the profile with unchanged geometry. The assumption of electrical profiling is the constant depth of investigation.

  • Resistivity or Surface Resistivity Services

    Surface resistivity is another non-destructive geophysical survey method used to investigate subsurface conditions. Surface resistivity can produce a detailed profile of the subsurface even in clay soils. Low ground resistivity is associated with clay soils, moist versus dry soils, buried metal, and other conductive materials. High ground ...

  • Resistivity Studies

    Geophysical studies using resistivity method are based on the determination of electrical resistance changes of the ground. These changes are natural (geological) or anthropogenic, and have a resistance different from the surrounding ground.

  • Resistivity Surveys

    Geophysical surveys, which use geoelectrical methods base on the variation of electrical parameters of the soil. To understand the phenomena in ground-rock medium, in which electric current flows, it must be realized that such substrate resists while electric current flows through it. According to Ohm's Law, resistance R is directly proportional ...

  • Resistivity Surveys by Tomography Technique

    Electrical resistivity tomography ERT is also known as resistivity imaging. This method is combination of electrical sounding and profiling because surveys are done along the profile and with increasing depth of investigation.

  • Electrical Resistivity Measurements

    Electrical Resistivity measurements are performed by placing multiple electrodes in contact with the soil or rock. Current is transmitted and received between pars of the electrodes. The surveys can be performed as traditional, single Vertical Electrical Soundings or with multi-channel systems to produce continuous resistivity cross-sections of ...

  • Resistivity Surveys by Sounding Technique

    Resistivity soundings is basic resistivity technique. This technique bases on the relegation of current electrodes from the potential electrodes in subsequent step to increase the depth of investigation. The point for which the measurement is made is in the middle between the potential electrodes.

  • Electrical Resistivity Imaging Geophysical Surveys

    Electrical resistivity imaging geophysical surveys (also known as resistivity tomography, ERI or ERT) measure the resistivity properties of the sub-surface by assessing the potential drops between electrodes in a variety of configurations, depending upon the type of geophysical survey data required. Electrical resistivity surveys can be completed ...

  • Geoelectrical surveys

    The measurement of electrical resistivity of the subsurface is one of the oldest geophysical methods (VES). It was developed during the late 1980s and the early 1990s as an electrical 2D and 3D imaging method for mapping the resistivity distribution in the subsurface CVES/ERT. Electrical resistivity is effective for shallow subsurface mapping at a ...
